No, Nickel has 2 electrons in its outermost shell! Look at the Periodical Table!!
Correction: The first answer was indeed correct. Ni = [Ar] 3d8 4s2 and if you count the number of valence electrons in each level, it comes up to ten. I just had a chemistry test on this, and I thought it was two at first too, but it's not. Don't think it's two unless you want to get the wrong answer.
I am not sure ,but the valency of nickel might be 2,but not according to Periodic Table,and who wrote this to look at periodic table?May be S/he has own periodic table in whick Nickel has 2 electrons in outermost shell.
6 valence electrons

Eight - it has a full outer shell of electrons.
Nickel has two unpaired electrons.
There are 27 valance electrons.
2 valance electrons
Iodine has 7 valance electrons
They have different numbers of valance electrons
6 valence electrons
6 valence electrons
there are six
Two.
